Unfortunately, there are no quick fixes. Therapy is the best option. If the college has a psych department, maybe they can offer some sessions there?
I have 2 childhood memories that have no negative overtones, and they are very young...15 months...the rest are bits and pieces of bad experiences.
But I am making progress and healing...just slow and steady...I hope you find what works for you.
I did have alot of memory issues when I was in college, I used an herbal suppliment.
